will index the digital display through the measurement sequence (see
“Measurement Indexing—without Fuel Flow Option” on page 12). To
exit the Manual indexing mode and return to the Automatic indexing
mode, either tap the
LF
button and then tap the
STEP
button or wait 15
minutes (see “How to Change Views” in the front of this manual). You
may disable the Automatic indexing mode. See “Personalizing” on page
40.
LeanFind Mode—Leaning Rich of Peak
JPI’s EDM-760/790 provides two methods of leaning:
lean
rich of peak
(LEAN R)
or
lean of peak
(LEAN L)
.
The standard
method is to lean about 20° rich of peak. With the advent of GAMI
injectors it is now possible to set the mixture lean of peak—saving
fuel and running the engine cooler. Teledyne Continental recommends
lean of peak for the Malibu. This manual primarily describes the rich
of peak method, and provides the procedure for the lean of peak
method. The factory default
method is set to rich of peak, but you can
change this to lean of peak. See Changing the Alarm Limits Procedure
on page 49.
Simply pre-lean, tap the
LF
button and begin leaning.
Upon
reaching cruise configuration, you will use the LeanFind mode to
identify the first cylinder to reach peak EGT.
A more detailed explanation of the LeanFind procedure follows this step-
by-step procedure.
